VENDING MACHINE WI'IH Application filed September To all whom it may concern:

Be it known that I, DANIEL L. CHANDLER, a citizen of the United States, residing at Fitchburg, in the county of. Worcester and State of Massachusetts, have invented new and useful Improvements in Vending Machines with Return-Coin Mechanism, of which the following is a specification.

This invention relates to a machine for vending articles and is of a character in which manually operable mechanism is provided which is rendered operable by means of a coin inserted in the casing of the machine.

The object of the invention is to provide a simple and effective slot machine for vending articles which will operate when a coin is deposited therein to deliver one of the articles to the party depositing the coin, but

which, in case there are none of such articles in the machine, or in the event that any of said articles are not of a predetermined size or diameter, will eject the coin from the machine so that the party who has deposited thecoin may obtain possession thereof. In the event that there are no articles in the machine, the party receives back his coin. In the event that the article or articles are not of a predetermined size or diameter the party who deposits the coin will receive the undersized article and also his coin, but if the articles are of the proper diameter or size, the coin will be retained by the machine and the article delivered to the depositor of the coin.

The machine of this invention also has an attachment for operating an advertising de vice which will'display a different card or plurality of cards for each time that themachine is operated.

Another object of the invention is to provide a construction whereby the coin controlling and article feeding mechanism may all be mounted upon a plate constituting the top ofv the casing of the machine for convenience in manufacture and repairs. 4 In the device of this invention the article which is to be vended if it is of a predetermined size ordiameter renders the mecha nism for ejecting the coin from the machine inoperable for that purpose and the coin is deposited in a receptacle provided for that purpose in the machine, but when the articles are exhausted from the machine or for any reason do not feed to the delivery mechanism magazine for articles.

RETURN-COIN MECHANISM.

17, 1921. Serial No. 501,476.

so as to be ejected from the machine, or if they are below a predetermined diameter, then the mechanism for ejecting the coin from the machine becomes operative.

If no coin is placed in the machine, then themanipulation of the crank whereby the article is ejected from the machine and the coin deposited in the coin receptacle becomes inoperative.

The invention consists in a machine of the character set forth. of mechanism' which upon the deposit of a coin in the machine is operable to eject the coin from the machine when the article to be vended is not ejected therefrom, or when the article which is ejected therefrom is of less than a predetermined diameter or size, but which, when a coin is deposited in the machine and the machine ejects an article of predetermined size therefrom will deposit the coin ina coin receptacle within said machine.

The invention further consists in certain improved mechanism for operating the ad vertising medium so as to display different advertising cards each time that the crank handle of the machine operates the mechanism for vending an article. i

The invention further consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims.

Like numerals refer to like parts through out the several viewsof the drawings.

In the drawings, 10 is the casing of the machine and 11 the top of said casing which is rigidly and detachably fastened to the casing and has mounted thereon upon the underside the coin controlling and article feeding mechanism and upon the upper side, the magazine 12 for holding the articles to be fed and also the movable advertising de vice 13"." The magazine 12 consists of a cylindrical glass container 14; which rests upon the top 11, its lower edge being encircled by a ring 15 forming a part the top 11. The container 14 is provided .with a top lexivhich consists of an annular into; which the upper edge of the. projects and of a detachable cover '18 which is fastened to the flange 17- by a staple 19 andpadlockQO, thehasp of the padlock extending through a hole provided in an ear2l which projects upwardly froin a-nd is fastened to the flange 17. The flange 1? container acts as a clamp to secure the container 1-4 to the top 11 and is fastened to the top by a plurality of vertical rods 22 which pro jec t through the flange 17 and have screwthreaded engagement at 1 their lower ends with the top 11 as illustrated in Fig. 5. The cover 18 is slotted at 23 and'the legs of the staple'19 project through saiclslcts so that when the padlock is locked, the" cover 18 will be secured to the flange" on one side thereof by said padlock and on the other side-thereof by tongue24 form'- ing that portion of thecover lying between the slots 23. A' guide member 25 is provided in'the magazine 12 which is cylindrical and has a conical top 26. Said guide member 25 is provided with ears 27 slotted at 2 8 and through these slots the rods 22 project. The cars 27 rest upon spiral springs 28 which, in turn, rest upon a guide plate 29 fast to the cover 11. The guide plate 29 is bevelled inwardly at 30 to guide the articles from the container through a hole 31 provided in the cover 1.1."The

guide member 26 is provided with. a recessed portion 32, the object of the guide member being to guide the articles tobe vended in such a manner that they will not become blocked. but will feed freely downwardly through the opening 31 and into a tubular holder 2 which extends downwardly from the underside of a carrier slide 84.

The carrier slide 341 is arranged to slide in ways 3-5 formed upon the underside 'of the top 11 and a reciprocatory motion is imparted tosaid slide to feed the which) flange 17 from the magazine out'of the machine by a rod 36 constituting anactuating member which is slidably mounted in a bearing 37 forming a part of the slide 34 The front end of the rod 36 is provided with :1 head 38 which has a vertical slot 39 therein in which is slid-ably located a crank pin 40 fastened to a crank 41 on a shaft 42. The crank shaft 12 is rotatably mounted in bearings 13 and M -fast to the underside of the top 11, and is prevented from moving 1on gitudinally thereof by said crank and by a collar fast thereto and contacting with the end of the bearing 44:. The collar 45 has one end of a spring 16 attached thereto by means of a screw 47, the other end of the spring being attached to the top 11 by a screw 18. A crank handle iQ is fastened 'to the outer end of the shaft 42 so that by rotating the crank shaft 42 by means of the crank handle 49 areciprocatory motion' will be imparted to the rod 56 by the crank pin 40. The spring 46 acts to to tate the shaft .12 row a, Fig. 2. and a pin 50 strikes against the upper'surface of the topul'ly and limits the distance to which the crank shaft 42 can be rotated by the spring 16. The rod 35 is locked. to theslide 34 by a coin-when it 's dropped into the machine in therfollow-' ing manner:A 'coin'chute 51fis fastened to the top 11 and projects upwardly therefrom. being provided with a reverse curved slot :52 which extendsthrough the top 11 and terminates at its lower end in line with vertical coin slot in the carrier slide 341-. The coin when dropped into. the chute 51 descends through the slot 52 and passes Intov the slot 53 inthe carriersllde and rests upon a stop finger 55 as illustrated in Thestop finger 5.5 is pivoted at 56.to the carrier slide 34 and isv adapted to alternately engage ears 5'?- and 58 on a stop plate 59 which is fast to- The notch 60 has a shoulder'el substantially.

atxright angles to the median longitudinal line of said actuating member. An auxil iary coin chute 63 is provided upon the carrier slide 34 which has two vertical passages 64' and 65 provided therein; The passage 64.

guides thecoin to a coin receptacle 66, and the passage 65. guides the coin into a chute 67 which empties onto. a shelf 68 front of the machine outside the leasing.

The auxiliary chute ispositioned witlr'the' passage'fi l'inline witlrthe coin slot 53 when in the direction of the u r-p ion the i there is an article of the proper size about to be delivered from the machine, and the passage 65 is in alignment with the coin chute 53 when there is no article delivered from the machine, or when thearticle which is delivered is of smaller dian'ieter than the standard. To accomplish this result, the auxiliary chute is moved longitudinally of the slide 34: to bring the passage 64; or the oassa 'e 65 into ali nment .with the lower end of the coin slot 58 and this is accomplished in the following manner :The auxiliary chute 63 has an arm 69 extending upwardly therefrom and fast to the front end of a sleeve 76 which is slidably mounted upon a pin 71 fast to the bearing 37 on the slide 3st and extending rearwardly from said bearing plate. The sleeve isprovided with a pair of laterally extending ears 72 "and 73 and between these ears a pin 74 projects, which pin is fastened to an arm 75 fast to a cam lever7 6 by means of a sleeve 77 which is mounted to rock upon a pin 78 fast to the slidei3d. The arm 75 and cam lever 76 are thus adapted to rock as one piece upon the pin 78 as a center or pivot. A spring 7 9 is fastened to the cam lever 76 and tends to move .said cam lever toward the right, F ig. 2, in orderto move a laterally extending finger 80 on the outer end of said cam lever 7 6 toward the center of the article holder 33, and through aslot 81 in the side of said article holder. A bracket 82 is fas tened to the underside of the top 11 and has fixed thereto a pair of plates 83 and '84. VVhen'the slide 34 is in its rearward position as in F ig. 2- the plate 83 projects across the tubular article holderand the article 85 rests upon said plate 83, the holder tube 33 .being slotted at 86 to allow the same to slide forward away from the plate 83 and backward into alignment therewith. The plate 84 is located beneath the tubular holder 33 so that when the carrier slide 34: is in its forward position, the article 85 will drop to the position illustrated in Fig. 5 in dotted lines. Then when the slide is pushed back from its forward to its rearward position, the article 85 will be carried by the holder 33 backwardly and off of the plate 84 and will drop out of the tubular holder on to the chute 67 and will roll down said chute and on to the shelf 68.

The device, which determines whether the coin is to be deposited in the receptacle 66 or whether it is to be ejected from the machine consists of a cam plate 87 illustrated in detail in Fig. 7. This plate is fastened to the underside of the top 11 and is provided with a pluralityof cam paths. l Vl'ien the slide at is in its rearward position, a pin 88 fast to the cam lever 76 is located relatively to said cam plate in the position illustrated in Fig. 7. Assuming that there is an article of the standard size or diameter which is being fed, then the lever 76 will be held in the position illustrated in Fig. 2 by the finger 80 resting against the periphery of the article 85 with a spring tension caused by the spring 79, and as the slide moves forward, the pin 88 will move with the lever 76 and pass to the left of the cam finger 89 on the cam plate 87 Fig. 3 and during the latter part of the forward motion of said slide, the pin 88 will ride up on the side 90 of the finger 89 and the lever 76 will be moved toward the left, F ig. 3, to release the article 85 and allow it to drop downwardly in the holder 33 onto the plate 84. Then as the slide 34!; moves backwardly, the article 85 will be pushed off of the plate 84 and will drop into the receptacle 67 while the pin 88 upon the lever 76 will return to the position illustrated in Fig. 2.

Assume now that there is no article in the article holder when the slide 34: is moved forward. In that ca e or in the event that the article is of a smaller diameter than standard, the pin 83 will move along the path 91 of the cam plate 87 being caused so to do by the spring 79 and by the forward motion of the slide 34 and this will. cause the cam lever to rock toward the right as illustrated in l, thus rocking the arm 75 toward the front of the machine and this will more the sleeve 70 forwardly carrying the auxiliary chute 63 forwardly and bringing the passage 65 therein into ali nment with the coin chute slot 53 so that the coin will then be delivered down the passage 65 onto the chute 67 and will roll out onto the shelf 68, but when the article 35 is of the ri 'ht size, then the cam lever 76 will remain substantially inthe position illustrated in Fig. '2 until the pin contacts with the side 90 of the cam finger 69 whereupon the finger 80 will be moved slightly to release the article, and the passage 64 of the auxiliary chute will remain in alignment "with the coin slot- 53 so that as the coin is dropped, it will pass down the passage 6 and into the receptacle 66.

hen a coin has been deposited in the machine as illustrated in F 5, and it rests in the position therein shown and the operator moves the crank handle 49 to bring the slide 34 forwardly, it is desirable that the slide should be caused to make its full forward movement before it can return to its rear ward position as illustrated in 2 and this desirable result is secured by means of a latch 92, Fig. 5, which is pivoted at 93 to the coven 11 and is provided on its under edge with teeth 94 and with an inclined forward portion 95 on its under edge. The latch 92 is held downwardly against a stop screw 96 by a spring 97. It will be seen that the operation of this locking latch is as follows :-ll hen the slide is moved forwardly, the upper edge of the coin 54: will engage the inclined edge 95 and will lift the latch slightly, and upon further forward movement, the edge of the coin will be engaged by the different teeth 9% which are so shaped as to prevent the slide from returning as long as there is a coin 54: located in the coin slot 53. Upon arriving at its forward position, however, the stop finger 55 will engage the ear 58 and will be moved to open the lower end of the slot 53 and at the same time the coin will be pushed down out of said slot by the action of the spring 97 and latch 92, whereupon the slide will be free to return to its rearward position.

The coin receptacle 66 is locked inside the casing by a vertical rod 98, the lower end of which enters a hole 99 in a base 100 to which base the casing 10 is fastened. The upper end of the rod 98 has a plate 101 fast thereto which projects from said rod toward the center of the cover 18 and beneath the outer edge of said cover; said plate has an car 102 thereon which projects downwardly through a slot 103 in the flange 17 so that when the cover 18 is locked in place by the padlock 20, the rod 98 will be locked in position so that the coin receptacle cannot be withdrawn from the casing.

The advertising device consists of a cylinder 104; rotatably mounted upon the top 11 and within a stationary cylinder 114i fast to the top 11 and provided with a vertical )pening 113 through which advertising cards on the cylinder 10a can be seen as said cylinder is rotated step by step as hereinafter described, and having a shaft 105 fast thereto and projecting downwardly through said top. The said shaft is rotated by a link 106 connected at one end thereof to the slide 84c and at the other end thereof to a pawl carrier 107, said pawl carrier being pivotally mounted upon the shaft 105 and having a feed pawl 108 mounted thereon and adapted to engage a toothed ratchet 109 for the purpose of imparting a rotary motion to said toothed ratchet, which, being fastened to the shaft 105, will cause said shaft to rotate in the direction of the arrow 7), Fig. 2. The shaft 105 is prevented from rotating in a direction reverse to that of the 'arrow 7) by a. locking pawl 110. r

The carrier slide is provided with two vertical pins 115 projecting upwardly therefrom through the hole 31 and into the bottom of the container 1 1 which serve to agitate the articles in the lower portionof the container 1 1- and prevent their failing to feed downwardly out of said container.

In the following claims the words"predetermined size and predetermined diameter have been used in connection with the article which is being vended. These words are not intended to limit the article being vended, as set forth in said claims, to an absolutely accurate or standard size, as the mechanism is constructed to deliver articles varylng somewhat in size and at the same time depositing the coin in the coin receptacle in the machine, but when the article is of substantially smaller diameter than the diameter of the standard size article intended to be vended in the machine, or when there is no article in the article holder, then such an article will be delivered from the machine and the coin will also be delivered to the user of the machine.

The general operation of the mechanism hereinbefore specifically described is as follows :-Assuming the parts to be in the relative positions illustrated in Fig. 2 and that without inserting any coin in the machine the crank handle 19 is operated, the only result will be to rock the shaft 42 and through the crank arm 41 and crank pin 40 to cause the rod 36 to be moved forwardly and backwardly in the carrier slide 34. Now if a coin is dropped into the coin chute 51 it will pass downwardly in the curved slot and be deposited in the coin slot 53 in the slide 34: resting upon the stop finger 55 and in alignment with the passage 64 in i the auxiliary coin chute 63.

Assuming now that an article 85 of the standard size is resting in the tubular holder 38 upon the stationary plate 83, the cam lever 76 will then be in the position illus trated in Fig. 2 with the finger not Dressed a ainst the article. Now u on iving the crank handle 49 a rotary movement, the rod 36 will be moved forwardly and as it is now locked to the carrier slide 34 by the coin, said carrier slidewill move forwardly carrying with it the article with the finger 80 pressed against it as in Fig; '3 which when the slide 3 1 has been moved to its forward positionwill drop onto the plate as illustrated in dotted lines, Fig.5, being released from theprcssure which holds it inthe tubular holder 33 by the finger 80 on the cam lever 76 moving away therefrom and being so moved by the pin'SS engaging the side of the cam finger 89. .During the forward movement of the carrier slide 34 the passage 64; of the auxiliary coin chute will be brought over the V-shaped guide plate 111 which is ailixed to the top of the coin receptacle 66 and the coin will thus, when dropped out of said passage 64, be guided through an opening 112 into said coin receptacle. During this forward movement the latch 92 has held the slide 34 from movement backward in case the crank handle should have been released or had not been sufficiently rotated to bring the slide 341- entirely forward. hen the slide 3 1 211- rives near the end of its forward movement, thestop finger 55 will engage the car 58 on .the stop plalel'iil and this will cause the stop finger hliito be rocked upon its pivot 56 until it is out of alignment with the com slot 53, thus allowing the coin 54 to drop, as hereinbefore described, into the passage 64 in the auxiliary coin chute and thence to be guided into the receptacle 66. Now upon releasing the crank handle 4L9, the spring 46 will rotate the shaft 42 in the opposite direction to that of the arrow at and will cause a pin 36 in the rod 36 to engage the forward end of'the slide 34, and cause it together with the parts mounted thereon, to returnto the relative positions illustrated in Fig. 2, and as the slide 3% returns to its rearward position, the tubular holder 33 will push the article 85 off of the plate 84 and said article will then drop 'down onto the chute 67 and be conveyed thereby to the shelf 68.

Assuming now that the article is smaller than standard size or that there is no article in the tubular holder 33, then upon a repetition of the movement of the crank handle 49, and assuming that there is a coin in the slot 53, the slide 34 will be moved forward asbefore, but this time the finger 80 of the cam lever 76 will project into the tubular holder 33 a sufficient distance so that when the pin 88 arrives at the finger 89, see Fig. 4, it will pass along the path 91 and during this movement, the spring 79 will rock the lever 76 so that it will rock the arm 75 and move the sleeve 70 along the pin 71 until the auxiliary chute is brought into the position illustrated in Fig. 4: with the passage in alignment with the coin slot Then when the stop finger 55 is withdrawn as hereinbefore described from the coin slot 53, the coin 54: will drop and pass down the coin passage 65 into the chute 67 and will roll down said chute onto the shelf 68.

During the forward movement of said carrier slide, the advertising cards on the cylinder 104 will be brought into view through an opening 113 in the stationar cylinder 114, and thus one by one the different advertising cards on the rotary cylinder will be brought into view.
